Title: Process for the production of l-carnitine from d, l-carnitinenitrile salts
Inventor: JAKOB HARALD
IPC: C07C227/34
Filed: 1992-04-10
Abstract: ABSTRACT            The production of L-carnitine by racemic fission of D,L-carnitinenitrile salts, in particular of D,L-carnitinenitrilechloride, using fission reagents that are optically active, separation of the diastereomeres, reduction of the diastereomeres that contain the L-carnitinenitrile to a salt of an acid that is not optically active, and saponification of the L-carnitinenitrile salt, this leading to a high yield and high enantiomere purity if N-acetyl-L-proline is used as the fission reagent.  When this is done, the (LL)-diastereomere is separated from the diastereomere mixture in crystalline form, and a second fractionating crystallisation stage, which has been customary up to this time, is eliminated.
Patent CA-2068239-A1 (CA)
Title: Back-up uninterruptible power system
Inventor: STICH FREDERICK A
IPC: H02J9/06
Filed: 1992-05-08
Abstract: BACK-UP UNINTERRUPTIBLE POWER SYSTEM                  ABSTRACT OF THE DISCLOSURE           A back-up uninterruptible power system has a power supply path from input terminals connected to AC power system lines to normally supply power to a load.          Upon the occurrence of a line fault, a static switch in the power supply path interrupts the connection between the AC power lines and the load and an inverter is turned on to provide power derived from an auxiliary battery through a transformer to the power supply path to supply AC power to the load.  By using the static switch, switching from line connection to backup power can be done quickly, within a half cycle, so that substantially no interruption of the output waveform is observed.  The inverter can be operated to provide a commutation pulse to the SCRs in the static switch to commutate an SCR which might otherwise continue conducting after the triggering signals to the gates are cut off and before the inverter supplies the AC power to the load.  A relay connected between the input terminals and the static switch is controlled to open relay contacts after the static switch has interrupted the current flow to the load, thereby providing positive electrical isolation of the AC power system from the uninterruptible power system while allowing the mechanical relay contacts to switch only during times of no current.  Line fault detection is carried out by creating a digital waveform composed of an average of prior cycles of the AC input waveform, converting the stored waveform to an analog signal, and comparing it with the present input signal in phase lock therewith to detect deviation of the input signal from the reference waveform.

Title: Corneal contact lenses
Inventor: SEIDNER LEONARD
IPC: G02C7/04
Filed: 1990-12-07
Abstract: In multifocal corneal contact lenses, the lenses of each pair (4a, 4b) have a different geometric configuration and/or distribution of focal zones (4c, 4d, 4e, 4f, 4g, 4h). The zones (4c, 4d, 4e, 4f, 4g, 4h) are distributed to provide vision corrections of different kinds for the two eyes of a patient under different illumination conditions. In monovision type corneal contact lenses, one or bothlenses (44a, 44b) is provided with one or more auxiliary correction zones (44e, 44h) each having a focal length different from the focal length of the major portion of the respective lenses. In any lens in accordance with the invention, the portion of the principal correction zones coextensive with the pupil of the respective eye covers more than approximately two-thirds (more preferably seventy-five percent and most preferably eighty percent) of the area of the pupil. This upper limit on the pupil area covered by the auxiliary zones is satisfied regardless of the disposition of the respective contact lens on the eye and regardless of the size of the respective pupil.
